Some years ago, my father, an attorney, took me to a fancy restaurant in New York City. When the bill arrived, there was a $1.50 charge for bread and butter. My father paid the bill, including that charge.
The next day, however, he sent a letter to the restaurant stating that the charge was uncalled for. Enclosed in the envelope was a bill for $500 for legal services.
Someone from the restaurant called immediately and asked, "What is this $500 bill for? We never ordered any legal services."
My father replied, "I never ordered any bread and butter."
The $1.50 was returned without delay.
